Delphi NC30 Series Non-Isolated Point of Load

DC/DC Power Modules: 12Vin, 0.9V-5Vout, 30A

The Delphi NC30 Series, 12V input, single output, non-isolated point of load DC/DC converters are the latest offering from a world leader in power systems technology and manufacturing ― Delta Electronics,

Inc. The NC30 series operates from a 12V nominal input, provides up to 30A of power in a vertical or horizontal mounted through-hole package and the output can be resistor- or voltage-trimmed from

0.9Vdc to 5.0Vdc. NC30 series has built-in current sharing control and multiple NC30/NC40 series modules could be paralleled together to provide even higher output currents. NC30 series provides a very cost effective point of load solution. With creative design technology and optimization of component placement, these converters possess outstanding electrical and thermal performance, as well as extremely high reliability under highly stressful operating conditions.

DESIGN CONSIDERATIONS

The NC30 is designed using two-phase synchronous buck topology. Block diagram of the converter is shown in

Figure 25. The output can be trimmed in the range of

0.9Vdc to 5.0Vdc by a resistor from trim pin to ground. A remote sense function is provided and it is able to compensate for a drop from the output of converter to point of load.

The converter can be turned ON/OFF by remote control.

Positive on/off (ENABLE pin) logic implies that the converter DC output is enabled when this signal is driven high (greater than 2.4V) or floating and disabled when the signal is driven low (below 0.8V). Negative on/off logic is optional and could also be ordered.

The converter provides an open collector signal called

Power Good. The power good signal is pulled low when output is not within ±10% of Vout or Enable is OFF.

The converter can protect itself by entering hiccup mode against over current and short circuit condition. Also, the converter will shut down when an over voltage protection is detected.

The converter has an over temperature protection which can protect itself by shutting down for an over temperature event. There is a thermal hysteresis of typically 30℃

FEATURES DESCRIPTIONS

ENABLE (On/Off)

The ENABLE (on/off) input allows external circuitry to put the NC converter into a low power dissipation (sleep) mode.

Positive (active-high) ENABLE is available as standard.

Positive ENABLE (active-high) units of the NC series are turned on if the ENABLE pin is high or floating. Pulling the pin low will turn off the unit. With the active high function, the output is guaranteed to turn on if the ENABLE pin is driven above 2.4V. The output will turn off if the ENABLE pin voltage is pulled below .8V.

The ENABLE input can be driven in a variety of ways as shown in Figures 26, 27 and 28. If the ENABLE signal comes from the primary side of the circuit, the ENABLE can be driven through either a bipolar signal transistor (Figure

26) or a logic gate (Figure 27). If the enable signal comes from the secondary side, then an opto-coupler or other isolation devices must be used to bring the signal across the voltage isolation (please see Figure 28).

FEATURES DESCRIPTIONS (CON.)

Input Under-Voltage Lockout

The input under-voltage lockout prevents the converter from being damaged while operating when the input voltage is too low. The lockout occurs between 7.7V to

8.6V.

Over-Current and Short-Circuit Protection

The NC series modules have non-latching over-current and short-circuit protection circuitry. When over current condition occurs, the module goes into the non-latching hiccup mode. When the over-current condition is removed, the module will resume normal operation.

An over current condition is detected by measuring the voltage drop across the high-side MOSFET. The voltage drop across the MOSFET is also a function of the

MOSFET’s Rds(on). Rds(on) is affected by temperature, therefore ambient temperature will affect the current limit inception point.

The unit will not be damaged in an over current condition because it will be protected by the over temperature protection.

Remote Sense

The NC30/NC40 provide Vo remote sensing to achieve proper regulation at the load points and reduce effects of distribution losses on output line. In the event of an open remote sense line, the module shall maintain local sense regulation through an internal resistor. The module shall correct for a total of 0.4V of loss. The remote sense connects as shown in Figures 29. o

GROUND

R load

Over Temperature Protection (OTP)

To provide additional over-temperature protection in a fault condition, the unit is equipped with a non-latching thermal shutdown circuit. The shutdown circuit engages when the temperature of monitored component exceeds approximately 130℃. The unit will cycle on and off while the fault condition exists.

The unit will recover from shutdown when the cause of the over temperature condition is removed.

Over Voltage Protection (OVP)

The converter will shut down when an output over voltage is detected. Once the OVP condition is detected, the controller will stop all PWM outputs and will turn on low-side MOSFET driver to prevent any damage to load.

Current Sharing (optional)

The parallel operation of multiple converters is available with the NC30/NC40 (option code B). The converters will current share to be within +/- 10% of each other. In addition to connect the I-Share pin together for the current sharing operation, the remote sense lines of the paralleled units must be connected at the same point for proper operation. Also, units are intended to be turned on/enabled at the same time. Hot plugging is not recommended. The current sharing diagram show in

Figure 30.

Output Voltage Programming

The output voltage of the NC series is trimmable by connecting an external resistor between the trim pin and output ground as shown Figure 31 and the typical trim resistor values are shown in Figure 32. The output can also be set by an external voltage connected to trim pin as shown in Figure 32.

Power Good

The converter provides an open collector signal called Power

Good. This output pin uses positive logic and is open collector. This power good output is able to sink 5mA and set high when the output is within ±10% of output set point. The power good signal is pulled low when output is not within

±10% of Vout or Enable is OFF.

Output Capacitance

There is no output capacitor on the NC series modules.

Hence, an external output capacitor is required for stable operation. For NC30 modules, two external 6.3V/680μF output low ESR capacitors in parallel (for example, OSCON) are required for stable operation.

It is important to places these low ESR capacitors as close to the load as possible in order to get improved dynamic response and better voltage regulation, especially when the load current is large. Several of these low ESR capacitors could be used together to further lower the ESR.

Please refer to individual datasheet for the maximum allowed start-up load capacitance for each NC series as it is varied between series.

Voltage Margining

Output voltage margining can be implemented in the

NC30/NC40 modules by connecting a resistor, R margin-up

, from the Trim pin to the ground pin for margining up the output voltage. Also, the output voltage can be adjusted lower by connecting a resistor, R margin-down

Reflected Ripple Current and Output Ripple and

Noise Measurement

The measurement set-up outlined in Figure 35 has been used for both input reflected/ terminal ripple current and output voltage ripple and noise measurements on NC series converters.

THERMAL CONSIDERATION

Thermal management is an important part of the system design. To ensure proper, reliable operation, sufficient cooling of the power module is needed over the entire temperature range of the module. Convection cooling is usually the dominant mode of heat transfer.

Hence, the choice of equipment to characterize the thermal performance of the power module is a wind tunnel.

Thermal Testing Setup

Delta’s DC/DC power modules are characterized in heated vertical wind tunnels that simulate the thermal environments encountered in most electronics equipment. This type of equipment commonly uses vertically mounted circuit cards in cabinet racks in which the power modules are mounted.

The following figure shows the wind tunnel characterization setup. The power module is mounted on a test PWB and is vertically positioned within the wind tunnel.

Thermal Derating

Heat can be removed by increasing airflow over the module. To enhance system reliability, the power module should always be operated below the maximum operating temperature. If the temperature exceeds the maximum module temperature, reliability of the unit may be affected.

The maximum acceptable temperature measured at the thermal reference point is 125 ℃.

This is shown in

Figure 36 & 41.
